Abstract
We show a method to form radially and azimuthally polarized beams as well as higher order polarization singularities by superposition of optical vortices with opposite topological charges obtained by optical parametric amplification. The proposed method could find applications in optical trapping of particles, nonlinear optics experiments, and laser material processing.
